Abstract

L'invention concerne une structure profilée d'écoulement d'air présentant un bord d'attaque profilé (164) ayant, suivant une ligne de bord d'attaque (164a), un profil en serrations présentant une succession de dents (30) et de creux (32), caractérisé en ce qu'elle comprend une région (52) poreuse acoustiquement absorbante localisée vers le fond des creux (32).A profiled air flow structure having a profiled leading edge (164) having, along a leading edge line (164a), a serrated profile having a succession of teeth (30) and hollow (32), characterized in that it comprises an acoustically absorbent porous region (52) located towards the bottom of the hollow (32).
